The adequacy of performance attainments depends upon the personal standards against which they are judged
Albert BanduraPeople who underestimate their capabilities also bear costs, although, as already noted, these are more likely to take self-limiting rather than aversive forms. By failing to cultivate personal potentialities and constricting their activities, such persons cut themselves off from many rewarding experiences. Should they attempt tasks having evaluative significance, they create internal obstacles to effective performance by approaching them with unnerving self-doubts
Albert BanduraSelf efficacious children tend to attribute their successes to ability, but ability attributions affect performance indirectly through perceived self-efficacy
Albert BanduraPeople who are burdened by acute misgivings about their coping capabilities suffer much distress and expend much effort in defensive action... they cannot get themselves to do things they find subjectively threatening even though they are objectively safe. They may even shun easily manageable activities because they see them as leading to more threatening events over which they will be unable to exercise adequate control.
